My husband and I both got Lumia 900s a week ago. We have been trying to troubleshoot the echo/feedback issue and poor call quality ever since. We ended up returning his phone for another one which was some improvement but there is still a problem with both of our phones.

We thought the echo, distortion, and feedback could be cured by keeping our volume down but people we talk to say that doesn't completely fix it and we can't hear the person we're talking to with the volume too low.

Everyone we talk to comments that they hear themselves echo when talking to us and end the conversation pretty quickly. This is happening with the volume down to 5 or 6.

Does anyone have more information about this? We can't have phones that we can't talk on even if the OS is great.

There is already a topic that addresses this issue so you aren't the only one. I have also experienced this issue on one occasion, it's unfortunate because other than the echo the call quality is top of the line. Since the phone has only been out for a week now don't be too surprised to see Nokia make several software updates addressing issues that currently effect the device.

My opinion: if you like the device keep it and wait for software updates. Nokia is usually very timely with their updates.
If you have other regrets about buying the device then return it, but just know that the Lumia 900 will continually grow better.

Yes you still can, 7 was actually too loud for me. I end up using 5 of 10.

Ok I will try that today. Thanks for the heads up.

So are we thinking the secondary mic for noise canceling is picking up the other person's voice in the ear piece and that's what they are getting as the echo? My one buddy said he would speak and then hear himself echo 3-4 seconds after.

I send my phone to Nokia care. And they fixed this issue. The fix log says they updated the software and did all quality test. YES, now I have WP 7.8 on my Lumia 900 installed by Nokia Care. I don't think they did any hardware fix for this. @AT&T
